Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.

AfterAir Duct Cleaning Company in South El Monte, CA
Air duct cleaning in South El Monte typically runs $350 – $650 for a whole-home system, with most jobs scheduled within a week and completed in one afternoon. We’re Hollis Air Duct Cleaning, and we’ve learned that homes here aren’t like homes in other San Gabriel Valley cities. South El Monte’s combination of 1950s-60s tract housing, low-pitch attics, and heavy freeway exposure from the 60 creates duct contamination we don’t see anywhere else. If you’re seeing black streaks on your return grilles or smelling exhaust when the AC kicks on, that’s not normal. Call us at (361) 326-5060 and we’ll give you a written price before any work starts.
Why South El Monte Homes Are Different
Most of South El Monte’s single-family stock went up fast in the 1950s and 1960s, and a surprising number still run on original galvanized steel or early flexible ducting that’s now 50 to 70 years old. That ductwork was never designed for the particulate load this city sees today. The 60 Freeway cuts right through South El Monte, and the San Gabriel Valley basin traps ozone and fine particulate matter against the mountains. We’ve pulled apart systems on the west side near Peck Road and found interior walls coated with a greasy, black film, a mix of brake dust, diesel soot, and cottonwood debris that vacuuming alone won’t touch.
The attics here are another factor. Low-pitch construction with limited clearance means our technicians work in tight spaces, often on their knees, maneuvering Rotobrush rotary systems and Nikro negative-air equipment where there’s barely room to turn around. It’s a two-person job by necessity, not preference. And because much of this ductwork is uninsulated or has degraded insulation, temperature swings in the attic have made the metal brittle and the joints leaky. We see rodent damage too, chewed flex duct in eaves and corners where rats have found entry points through soffits that settled decades ago.
Our Main South El Monte Services
Homeowners in South El Monte call us most often for these three jobs. Each has its own page with full pricing, process details, and what to expect.
Air Duct Cleaning in South El Monte
Our full-system cleaning uses a Rotobrush rotary brush system paired with Nikro negative-air machines to dislodge and extract buildup from every branch line, trunk, and return. In South El Monte, we pay special attention to return plenums and filter grilles, where that freeway soot concentrates thickest. We run before-and-after camera inspections so you see what came out. Every job gets a written price upfront and is covered by our 365-Day Done Right Promise. Air Duct Cleaning in South El Monte has complete pricing and scheduling details.
Dryer Vent Cleaning in South El Monte
Dryer vents in older South El Monte homes often run through walls or under low-slope roofs with multiple bends that trap lint. We use high-velocity air tools and rotary whips to clear the full run from appliance to termination, then verify airflow with a meter. Blocked dryer vents are a genuine fire hazard, and in this climate, lint compacts fast. We don’t leave until the vent tests clear. Full process and pricing are on our Dryer Vent Cleaning in South El Monte page.
Duct Sealing in South El Monte
With original ductwork this old, sealing often matters more than cleaning. We apply mastic sealant and mechanical fasteners at every joint, register boot, and plenum connection, then pressure-test the system to confirm leakage is below industry standards. Sealing stops conditioned air from bleeding into hot attics and pulls less freeway dust into the living space through negative pressure. Our Duct Sealing in South El Monte page breaks down when sealing makes sense versus replacement.
